The slope of the line passing through the points (-5,5) and (5,8) is 0.3.
The slope of a line is the rate at which it rises or falls as it moves from left to right. It is defined as the change in the vertical distance divided by the change in the horizontal distance between any two points on the line.
The slope of a line passing through two points (x₁,y₁) and (x₂,y₂) can be calculated using the slope formula:
slope = (y₂-y₁)/(x₂-x₁)
Using the coordinates (-5,5) and (5,8), we can plug in the values to get:
slope = [tex]\frac{(8-5)}{(5-(-5))}[/tex]
slope = [tex]\frac{3}{10}[/tex]
slope = 0.3

If a value of 80.2° is added to the data, how does the range change?
The range stays 47°.
The range decreases to 47°.
The range stays 48°.
The range increases to 50°.
Answer:
The range stays 48°
Step-by-step explanation:
The range is the difference between the highest and lowest values in the data set. Before adding 80.2°, the highest temperature is 105° and the lowest temperature is 57°, so the range is 105° - 57° = 48°.
After adding 80.2°, the highest temperature becomes 105° + 80.2° = 185.2° and the lowest temperature becomes 57° + 80.2° = 137.2°. So the new range is 185.2° - 137.2° = 48°.
Therefore, the range stays the same at 48°. The answer is: The range stays 48°.

A dog's body temperature (t), in degrees Fahrenheit (°F), is considered normal when the value of the expression below is no more than 0.75.
|t - 101.75|
A dog's body temperature is 101.2°F. Based on the expression, which statement about the dog's body temperature is true?
A. Since normal body temperature is from 100.25°F to 103.25°F, the dog's body temperature is considered normal.
B. Since normal body temperature is from 100.25°F to 103.25°F, the dog's body temperature is not considered normal.
C. Since normal body temperature is from 101°F to 102.5°F, the dog's body temperature is considered normal.
D. Since normal body temperature is from 101°F to 102.5°F, the dog's body temperature is not considered normal.
C. The dog's body temperature is regarded normal because the range for a healthy adult is 101°F to 102.5°F.
What exactly is value?
Value is the appraised, monetary, or material worth of a good, service, or asset. Several ideas are associated with the word "value," including shareholder value, company value, fair value, and selling price.
The phrase to assess whether a dog's body temperature is acceptable or not is:
|t - 101.75| ≤ 0.75
When we replace the specified value for the dog's body temperature, we obtain:
|101.2 - 101.75| = |-0.55| = 0.55
The body temperature of the dog is regarded as normal because 0.55 is less than 0.75.
Option C, however, is the one that accurately depicts the dog's core body temperature:

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 10 N acts on a certain object, the acceleration of the object is 5 /ms2. If the force is changed to 14 N, what will be the acceleration of the object?
The acceleration of the object when a force of 14 N acts on it will be 7 m/s².
We can use the proportionality relationship between force and acceleration to solve this problem. The relationship can be expressed as:
F = k a
where F is the force, a is the acceleration, and k is a constant of proportionality.
We are given that the force and acceleration are directly proportional, so we can set up a proportion using the given information:
10 N / 5 m/s² = 14 N / a
Solving for a, we can cross-multiply and simplify:
10 N * a = 5 m/s² * 14 N
a = (5 m/s² * 14 N) / 10 N
a = 7 m/s²
Therefore, the acceleration of the object when a force of 14 N acts on it will be 7 m/s².

The measure of arc ED is 78.7°
How to find the measure of an arc?An arc of a circle is a portion of the circumference of a circle. It is defined by two endpoints and the arc itself.
The measure of an arc is given in degrees or radians, and it is determined by the angle that it subtends at the center of the circle.
Since FC is the diameter and arc FB is equivalent to arc BC. We can say:
arc FB + arc BC = 180°
arc FB = arc FB = 90°
Also, arc ED is twice the measure of arc CD. We can write:
arc ED = 2 * arc CD
arc CD = (arc ED)/2
Since the sum arc FB and arc BC is 180°. We can say:
arc FE + arc ED + 0.5(arc ED) = 180°
62° + arc ED + 0.5(arc ED) = 180°
62° + 1.5(arc ED) = 180°
1.5(arc ED) = 180 - 62
1.5(arc ED) = 118

Ben's ball lands approximately 2.5 seconds after Andrew's ball.
How long after Andrew's does Ben's ball land?Since the value of parameter a is -5 for both balls, the height of each ball follows the equation:
h(t) = -5t² + vt + h0
where;
h(t) is the height of the ball at time t, v is the initial velocity of the ball (in meters per second), and h0 is the initial height of the ball (in meters).Let's assume that Andrew's ball is hit with an initial velocity of v1, and Ben's ball is hit with an initial velocity of v₂. We also know that Ben's ball reaches a maximum height 50% greater than Andrew's, which means that:
h_max₂ = 1.5h_max₁
At the maximum height, the velocity of the ball is zero, so we can find the time it takes for each ball to reach the maximum height by setting v = 0 in the equation for h(t):
t_max1 = v₁ / (2 x 5)
t_max2 = v₂ / (2 x 5)
Since Ben's ball reaches a maximum height that is 50% greater than Andrew's, we can write:
h_max2 = 1.5h_max1
-5(t_max2)² + v₂t_max2 + h0 = 1.5(-5(t_max1)² + v1 * t_max1 + h0)
Simplifying this equation, we get:
-5(t_max2)² + v₂t_max2 = -7.5(t_max1)² + 1.5v₁t_max1
We also know that Andrew's ball lands after 4 seconds, which means that h(4) = 0:
h(4) = -5(4)² + v1 * 4 = 0
-80 + 4v1 = 0
v1 = 80/4
v1 = 20 m/s
Solving these equations for t_max2 and v2, we get:
t_max1 = v1 / (2 x 5)
t_max1 = 20 / (2 x 5) = 2 s
t_max2 = 1.5 * t_max1 = 3 s
v2 = 1.5 * v1 = 30 m/s
To find the time it takes for Ben's ball to land, we need to find the time t2 when h(t2) = 0.
We can use the equation for h(t) with v = v2, h0 = 0, and solve for t:
-5t² + v₂t = 0
-5t² + 30 = 0
5t² = 30
t² = 30/5
t² = 6
t = √6
t = 2.5 s
Therefore, Ben's ball lands approximately 2.5 seconds after Andrew's ball.

write and solve a proportion to find the perimeter of a square when its side length is 12
Therefore, the perimeter of the square when its side length is 12 is 48 units.
What, for example, is a perimeter?The perimeter of an object is the space surrounding it. For instance, the yard around your house is fenced in. The perimeter of the barrier is its length. If the yard is 50 by 50 feet, your fence is 200 feet long.
Since a square has all equal sides, the perimeter of a square is just four times the length of one side. Therefore, the perimeter of the square when its side length is 12 is:
Perimeter = 4 x 12 = 48
To write a proportion to solve for the perimeter of a square when its side length is x, we can set up the following ratio:
12/x = 48/p
where p represents the perimeter of the square. We can cross-multiply to get:
12p = 48x
p = 4x
Now we can substitute 12 for x to find the perimeter when the side length is 12:
p = 4(12) = 48

The sum of the first 3 terms of a geometric sequence

Determine the value of r.
The value of r is approximately 0.62.
The sum of the first 3 terms of a geometric sequence is 30 1/2 and the sum of the 4th, 5th, and 6th term is 3 15/16. To determine the value of r, we can use the formula for the sum of a geometric sequence:
S_n = a_1 (1 - r^n) / (1 - r)
Where S_n is the sum of the first n terms, a_1 is the first term, and r is the common ratio.
For the first 3 terms, we have:
30 1/2 = a_1 (1 - r^3) / (1 - r)
For the 4th, 5th, and 6th terms, we can use the formula for the nth term of a geometric sequence:
a_n = a_1 r^(n-1)
So the 4th term is a_1 r^3, the 5th term is a_1 r^4, and the 6th term is a_1 r^5. The sum of these terms is:
3 15/16 = a_1 r^3 + a_1 r^4 + a_1 r^5
We can factor out a_1 r^3 to get:
3 15/16 = a_1 r^3 (1 + r + r^2)
Now we can substitute the expression for a_1 r^3 from the first equation into the second equation:
3 15/16 = (30 1/2) (1 - r) (1 + r + r^2)
Simplifying and rearranging terms, we get:
r^5 - 8r^4 + 15r^3 - 8r^2 + r = 0
This is a quintic equation, which cannot be solved algebraically. However, we can use numerical methods to find an approximate value of r. Using a graphing calculator, we find that r ≈ 0.62.
Therefore, the value of r is approximately 0.62.

La cofunción del seno de un ángulo es igual al coseno de su complemento. Similarmente, la cofunción del coseno de un ángulo es igual al seno de su complemento.
Entonces, para encontrar la cofunción de sec(y-π), primero encontramos el complemento de (y-π), que es (π/2 - (y-π)) = (π/2 - y + π) = (3π/2 - y).
Por lo tanto, la cofunción de sec(y-π) es igual al coseno de su complemento, que es el coseno de (3π/2 - y):
cos(3π/2 - y) = -sin(y)
Entonces, la cofunción de sec(y-π) es igual a -sin(y).

What is magnitude ?Magnitude refers to the size or amount of something, often measured numerically or on a scale. In mathematics, it is commonly used to describe the absolute value of a number or the length of a vector in a geometric space. Magnitude can also be used to describe the intensity or strength of physical phenomena, such as the magnitude of an earthquake or the magnitude of a force.
According to given information :To find the magnitude and direction of MN with tail and head points M(-3, -2) and N(4, 0), we can use the distance formula and trigonometry.
First, we can find the coordinates of MN by subtracting the coordinates of M from those of N:
MN = (4 - (-3), 0 - (-2)) = (7, 2)
The magnitude of MN is the distance between M and N, which can be found using the distance formula:
|MN| = √((7 - (-3))² + (2 - (-2))²) = √(10² + 4²) = √116 ≈ 10.77
Next, we can find the direction of MN by using trigonometry. The angle between MN and the positive x-axis (east) is:
θ = arctan(2/7) ≈ 16.26°
The direction of MN is 180° + θ (measured counterclockwise from the positive x-axis) because the tail point M is to the left of the head point N:
Direction of MN = 180° + 16.26° ≈ 196.26°
To convert this direction to a compass direction, we can subtract it from 360° and then divide by 4, rounding to the nearest degree. This gives:
Compass direction of MN = (360° - 196.26°)/4 ≈ 40.44°
Since MN is to the right of the y-axis (north-south), its direction is south of east, which is 90° - 40.44° = 49.56° east of south.
Therefore, its direction is south of east which is 49.56° east of south, the answer is not listed among the answer choices provided.

Which of the equation choices could represent the circle shown on the graph?
The equation that represents the circle shown in the graph is:[tex](x - 2)^2 + (y + 1)^2 = 9.[/tex]
What is circle ?
A circle is a shape in geometry that is defined as a closed curve that is formed by a set of points that are equidistant from a single fixed point called the center. The distance between any point on the circle and the center is called the radius of the circle.
The center of the circle appears to be at the point (2, -1) and the radius seems to be approximately 3 units.
Using the values of the center and radius, we can plug them into the general equation of a circle to obtain the equation that represents the circle:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
Substituting h = 2, k = -1, and r = 3, we get:
[tex](x - 2)^2 + (y + 1)^2 = 9[/tex]
Therefore, the equation that represents the circle shown in the graph is:[tex](x - 2)^2 + (y + 1)^2 = 9.[/tex]
Option D is the equation that represents the circle, which is[tex](x - 2)^2 + (y + 1)^2 = 9.[/tex]

A rectangular box with a volume of 60x^(6)y^(6)z^(10) width of 2x^(2)y^(3)z^(4) length of 10x^(3)y^(4)z^(5) units and a height, 2x^(2)y^(3)z^(4) units. Write an expression for its height
The expression for the height of the box is 3x^(1)y^(-1)z^(1) units.
The volume of a rectangular box is given by the formula V = lwh, where l is the length, w is the width, and h is the height. We are given the volume, width, and length of the box and we are asked to find the expression for its height.
Volume = 60x^(6)y^(6)z^(10)
Width = 2x^(2)y^(3)z^(4)
Length = 10x^(3)y^(4)z^(5)
Substituting the given values into the formula for volume, we get:
[tex]60x^{(6)}y^{(6)}z^{(10)} = (2x^{(2)}y^{(3)}z^{(4))}(10x^{(3)}y^{(4)}z^{(5))(h)[/tex]
Simplifying the right side of the equation, we get:
60x^(6)y^(6)z^(10) = 20x^(5)y^(7)z^(9)(h)
Dividing both sides of the equation by 20x^(5)y^(7)z^(9), we get:
h = (60x^(6)y^(6)z^(10))/(20x^(5)y^(7)z^(9))
Simplifying the fraction, we get:
h = 3x^(1)y^(-1)z^(1)
Therefore, the expression for the height of the box is 3x^(1)y^(-1)z^(1) units.

The variance of a sample of 169 observations equals 576. The standard deviation of the sample equals:
a. 13
b. 24
c. 576
d. 28,461
The standard deviation of the sample is 24. Therefore the correct option is, option b. 24.
The variance of a sample is the square of the standard deviation. In other words, the standard deviation is the square root of the variance. Therefore, to find the standard deviation of the sample, we need to take the square root of the variance:
√576 = 24
Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.
Like the variance, if the data points are close to the mean, there is a small variation whereas the data points are highly spread out from the mean, then it has a high variance.
So, the standard deviation of the sample of 169 observations and variance 576 equals 24. The correct option is b.

Find the final amount for an investment of $5,000 over 5 years at an annual interest rate of 6% if the interest is compounded quarterly.
The final amount for the investment of $5,000 is $ 6,749.29.
Compound interest:Compound interest is a type of interest calculation in which the interest earned on an initial principal amount is added to the principal, and the new total amount earns interest in subsequent periods.
This means that the interest earned in each period is based on the total amount, which includes both the principal and the accumulated interest from previous periods.
The formula used for compound interest:
[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]Where:
P = Initial investment
r = Rate of interest (as a decimal)
n = Number of compounds
t = Time period in years
Here we have
P = $5,000,
r = 6% = 0.06,
n = 4 (since the interest is compounded quarterly), and
t = 5 years.
Using the above formula
[tex]A = 5000(1 + 0.06/4)^{(4*5)[/tex]
[tex]A = 5000(1.015)^{20[/tex]
[tex]A = 5000(1.34985711)[/tex]
[tex]A =\$6,749.29[/tex]
Therefore,
The final amount for the investment of $5,000 is $ 6,749.29.
